“…Since the covalence and ionic chemical bonds strongly influence the magnitude of the nonlinearity. One can see that (3) begins from 0.2 × 10 −13 esu and get increase as the photon energy h increases up to 1.7 eV, after which (3) has a limit value of 1.62 × 10 −13 esu. The obtained absolute values of transmittance and reflectance are used to determine the complex refractive index (n* = n − ik) and the complex dielectric constant (ε* = ε 1 − iε 2 ) (where the real dielectric constant ε 1 = (n 2 − k 2 ) and the imaginary dielectric constant ε 2 = 2nk).…”

“…The third order of nonlinear polarizability parameter, (3) , socalled nonlinear optical susceptibility, is an important parameter, because it gives an indication about the strength of the chemical bonds between molecules of the prepared nanocrystalline thin film. The third-order nonlinear susceptibility of NiO film is calculated by using Eq.…”

“…Nanosized nickel oxide has demonstrated excellent properties such as catalytic [2], magnetic [3], electrochromic [4], optical and electrochemical properties [5]. Furthermore, nickel oxides can be used as a transparent p-type semiconducting layer [6] and are being studied for applications in smart windows, electrochemical supercapacitors [7] and dye sensitized photocathodes [8].…”

Ni nanoparticles of average size 70 nm were dispersed in a mixed solution of ethanol (100 ml) and a dispersant (Hypermer KD-2, HKD-2). The suspension was ultrasonicated for 90 min, then electrophoretic deposition (EPD) was performed with deposition times from 5 to 10 min at a constant potential of 180 V. The highest absolute value of the zeta potential was -32.5 mV at 1 wt% HKD-2. Coating of the Ni particles on an Ni plate was performed by use of a suspension with high conductivity. Important conditions for electrophoretic deposition of Ni particles on to an Ni plate are high conductivity of the suspension and a large absolute value of the zeta potential. Significant agglomeration of Ni particles was observed during deposition when the EPD time was increased.

The magnetic alloys of Cu-Fe (Cu 50 Fe 50 , Cu 80 Fe 20 and Cu 90 Fe 10 ) were prepared by a mechanical alloying method and their structural and magnetic behaviors were examined by X-ray diffraction and Mössbauer spectra. The magnetization curves did not distinctly show the saturation at 70 kOe for the concentrated alloys of Cu 80 Fe 20 and Cu 90 Fe 10 . The Mössbauer spectrum of Cu 80 Fe 20 at room temperature shows one Lorentzian line of the paramagnetic phase, whereas the Mössbauer spectrum of Cu 90 Fe 10 consists of a sextet Lorentzian line at room temperature and a centered doublet line. The Mössbauer spectra of Cu 90 Fe 10 measured in the temperature ranges from 13 to 295 K, implies that Cu 90 Fe 10 consists of two magnetic phases. One superimposed sextet corresponds to the ferromagnetic iron in Cu matrix and the other one indicates the superparamagnetic iron rich phase.
